Love them, can be somewhat shy and difficult to feed initially. Intial feeding may need to be live; balckworms, brine shrimp, even ghost shrimp. I would recommend planning to treat for internal parasites, if you have heard they can difficult, this is why. Great additon to a 75g, rarely if ever bothers anyone, but may nibble on your cuc; unless you have a real bully, most just leave them alone to do their thing.
